Boost your GT's fuel economy while adding an extra pony or two under the hood with Airaid's PowerAid Throttle body spacer. The easy to install spacer goes between your throttle body and intake tube. It features a patented Helix Bore design which spins the incoming air as it passes through the spacer. The spinning effect boosts the velocity of the air being sucked into your intake manifold. The result is better throttle response and mid-range power.
